#853 closed Bug (fixed)

transmission-(daemon|gtk) segfault when querying status

Reported by: icy Owned by: charles
Priority: High Milestone: 1.20
Component: Transmission Version: 1.11
Severity: Major Keywords:


The transmission daemon as well as the gtk frontend segfault when I query their status.

transmission-remote -t gtk -l => gtk frontend crashes daemon.get_stats_all() from the transmission python client => daemon segfaults

This is with the latest svn version on a amd64 ubuntu box.

transmission-daemon 1.10 from gentoo does not crash btw.


Program received signal SIGSEGV, Segmentation fault.

The bug was introduced in revision 5547 (which btw had an incomplete log entry).

The function ipc_addstat() in ipcparse.c was changed, but not the respective calls of said function in gtk/ipc.c and daemon/server.c The attached patch should fix the segfaults. Since function torrent_stat() in daemon/torrents.c now no longer returns a tr_stat object, it probably should be renamed.

I tested with the daemon, and it worked fine. I was not able, however, to test the GTK build, since I'm running things on my NAS.

r5579 should work better.

I didn't mean to check in the ipc files with r5547.
